Ipamorelin
Ipamorelin is the pentapeptide Aib-His-D-2Nal-D-Phe-Lys-NH2, studied as a selective agonist of the ghrelin receptor GHS-R1a, and the research catalog lists it at https://onesourcepeptides.com/product/ipamorelin.
Raun et al. (European Journal of Endocrinology, 1998, 139:552–561) described it as a growth-hormone secretagogue with a selective profile in early animal pharmacology, set against older peptides in the same class that also moved ACTH and cortisol in those experiments. Later papers treat it as a tool compound for ghrelin-receptor and growth-hormone-axis models. Mass is often cited near 711 Da.
The single-peptide listing is not the CJC-1295 no DAC blend, which adds a GHRH-receptor analogue in the same vial. Identity and purity are lot documents. This note does not give a dose or a human-use recommendation.
